C: CAUTION
•Wear work clothing, including a cap, protective goggles and protective shoes during operation.
•Remove contamination including dirt and corrosion before removal, installation or disassembly.
•Keep the disassembled parts in order and protect them from dust and dirt.
•Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, disassembly and replacement.
•Be careful not to burn yourself, because each part on the vehicle is hot after running.
•Be sure to tighten fasteners including bolts and nuts to the specified torque.
•Place shop jacks or rigid racks at the specified points.
•Before disconnecting connectors of sensors or units, be sure to disconnect the ground cable from battery.

B: INSTALLATION
1. RH SIDE
Install in the reverse order of removal.
Tightening torque (Spark plug):
21 N·m (2.1 kgf-m, 15.2 ft-lb)
Tightening torque (Ignition coil):
16 N·m (1.6 kgf-m, 11.7 ft-lb)
NOTE:
The tightening torque described above should be
applied to only new spark plugs without oil on their
threads.
In case their threads are lubricated, the torque
should be reduced by approx. 1/3 of the specified
torque in order to avoid over-stressing.
2. LH SIDE
Install in the reverse order of removal.
Tightening torque (Spark plug):
21 N·m (2.1 kgf-m, 15.2 ft-lb)
Tightening torque (Ignition coil):
16 N·m (1.6 kgf-m, 11.7 ft-lb)
NOTE:
The tightening torque described above should be
applied to only new spark plugs without oil on their
threads. In case their threads are lubricated, the
torque should be reduced by approx. 1/3 of the
specified torque in order to avoid over-stressing.
C: INSPECTION
Check the electrodes and inner and outer ceramic
insulator of plugs, noting the type of deposits and
the degree of electrode erosion.
1) Normal:
Brown to grayish-tan deposits and slight electrode
wear indicate correct spark plug heat range.

A: INSPECTION
Inspection and adjustment of valve clearance
should be performed while engine is cold.
1) Set the vehicle on a lift.
2) Remove the collector cover.
3) Disconnect the ground cable from battery.
4) Lift-up the vehicle.
5) Remove the under cover.
6) Lower the vehicle.
7) When inspecting RH side cylinders:
(1) Remove the air intake duct and air cleaner
case. take Duct.> Air Cleaner Case.>
(2) Remove the fuel tank protector (RH).
(3) Disconnect the connector of oil pressure
switch.
(4) Remove the ignition coil. IG(H6DO)-7, REMOVAL, Ignition Coil & Ignitor

(5) Remove the rocker cover (RH).
8) When inspecting LH side cylinders:
(1) Disconnect the battery cable, and then re-
move the battery and battery carrier.
(2) Disconnect the PCV hose and blow-by hose
from rocker cover (LH).
(3) Remove the fuel pipe protector (LH).
(4) Remove the ignition coil. IG(H6DO)-7, REMOVAL, Ignition Coil & Ignitor

5. Spark Plug
A: REPLACEMENT
1) Remove the battery and battery carrier.
2) Remove the air cleaner case.
3) Detach the connector from ignition coil.
4) Remove the ignition coil.
5) Remove the spark plug with a spark plug socket.
6) Tighten the new spark plug lightly with hand, and
then secure with a spark plug socket to the speci-
fied torque.
Recommended spark plug:
NGK: ILFR6B
Tightening torque:
21 N·m (2.1 kgf-m, 15.2 ft-lb)
7) Tighten the ignition coil.
Tightening torque:
16 N·m (1.6 kgf-m, 11.7 ft-lb)
NOTE:
•Be sure to place the gasket between the cylinder
head and spark plug.
•If the torque wrench is not available, tighten the
spark plug until gasket contacts cylinder head; then
tighten further 1/4 to 1/2 turns.
